How To Clean Basin Overflow ?

1. Why Should You Clean the Basin Overflow Regularly?

The basin overflow is typically located near the front edge of the sink or just below the faucet. It serves as a backup drainage channel—when the water level in the basin gets too high, it allows excess water to flow into the drainage system, preventing overflow onto your bathroom floor. However, since the overflow for basin is constantly exposed to moisture and lacks proper ventilation, it's prone to accumulating dirty water, soap scum, and bacteria. If not cleaned regularly, this hidden area can pose hygiene risks and cause unpleasant odors in your bathroom.

2. Step-by-Step Guide to Cleaning the Basin Overflow

Step 1: Initial Rinse

Pour a kettle of hot water or fresh tap water into the overflow opening. This helps soften grime and flush out loose surface debris.

Step 2: Surface Scrubbing

Dip an old toothbrush in a cleaning agent and scrub around the opening of the basin overflow cover, removing visible soap residue, limescale, and dirt buildup.

Step 3: Deep Cleaning

Mix approximately 50ml of white vinegar with a teaspoon of baking soda and pour it into the overflow hole. Let it sit for 10 minutes. You may notice bubbling or fizzing—that's normal and indicates the solution is working to dissolve internal gunk.

Step 4: Internal Flushing

Use a syringe or soft hose to inject warm water deep into the overflow channel. This will rinse out any remaining dirt or smell. Repeat the process a few times until the sink basin overflow ring is clean and odor-free.

3. Preventive Tips for Daily Maintenance

To keep your basin overflow clean for longer, consider the following tips:

• Lightly brush the overflow opening with a toothbrush once a month

• Pour in vinegar or baking soda water regularly to prevent odor buildup

• Avoid letting foam, hair, or toothpaste debris enter the overflow while washing your face or hair

• Consider installing a wash basin overflow cover or basin overflow cap—these not only block unwanted debris from entering but also serve as a stylish accessory to enhance the look of your sink

4. Final Thoughts
